Scott’s emulsion: what it is, what it is for, composition, indications

What is Scott’s Emulsion?

The Emulsion of Scott is a nutritional supplement used to treat health conditions caused by nutritional and vitamin deficiencies. This product has a viscous consistency, as it is made from cod liver oil.

It is a substance that provides important nutrients to the body. Although its original taste and smell were somewhat bitter, the most modern presentations have other, more pleasant aromas.

What is it for?

Scott’s Emulsion has therapeutic purposes ranging from a nutritional supplement in children to the improvement of psoriasis and the prevention of heart attacks.

This is because omega-3 has positive effects on the maintenance of the circulatory system, keeping blood vessels in good condition and free of obstructions.

However, as with any medicinal product, every benefit comes with risks. Cod liver oil can lead to hypervitaminosis if consumed too much, since vitamin A is not processed well and accumulates in the liver in dangerous amounts. In pregnant women it can cause hypertension in pregnancy.

It is also dangerous to consume it without purifying it, as it can cause contamination by cod toxins.

Although Scott’s Emulsion has had a lot of recent hype, this product has an age that dates back to the late 1800s. In fact, this vitamin complex is part of the line of commercial cod liver oils.

It is usually made with gadus morhua, as well as other species. These fats have had multiple manufacturers throughout history, and have their origins in Europe, whose seas are conducive to cod farming.

Cod is the raw material for Scott’s Emulsion. This oily substance has undergone a continuous renewal process in its formula and composition.

Given the need to preserve the environment, ways have been sought to make cod liver synthesized by artificial means in the laboratory, taking care that its nutritional properties are preserved, and therefore, its therapeutic qualities for which it is so known to consumers.

cod liver oil

This oil is one of many types of fish oils that contain high levels of fatty acids, such as omega-3. It also contains eicosapentaenoic acid and docosahexaenoic acid.

Also, this fat has vitamins A and D. The latter is known to help prevent rickets and other conditions caused by deficiency of this vitamin.

This emulsion works as a nutritional supplement that complements the diet of children by maintaining a healthy and balanced diet.

It is important to emphasize that cod liver oil is popular because of Scott’s Emulsion, but that this product was not the first nor the only one to introduce it.

Historically, the use of this oil is known to be quite old, having been manufactured since the time of the Vikings, in the remote regions of Scandinavia. In the 18th and 19th centuries, the Industrial Revolution saw the refinement and purification of its production on a larger scale.

Cod liver oil went through a continuous stage of refinement that gradually incorporated changes, although some features that can be described as traditional were maintained.

For example, this oil preserves its characteristic amber color, its smooth texture when savored, and its somewhat sour taste, which, many years ago, used to be linked to its medicinal properties.

The appearance of the cod liver oil in Scott’s Emulsion differs from the above description. It shares its flavor and texture, but not its colour, which is rather whitish. However, this mixture preserves its chemical properties, in which vitamins A and D are combined with omega-3.

Historical review

Scott’s Emulsion has a history dating back to the late 19th century, when in 1873 Alfred B. Scott left England for New York with his partner Samuel W. Bowne to present an innovation.

What was revolutionary about Scott was not the cod liver oil, which by then was already well known in the UK for its Nordic influences, but its taste, more tolerable than its competitors. It was this that earned him public acceptance.

By the 1890s, Scott had taken his brand internationally. The company, distinguished by the image of the man with the fish on his back, knew how to reinvent a recipe that was believed to be unbeatable.

The problem with this substance was the unpleasant taste for children, and for this reason, it was thought to modify the recipe in order to give it a taste as pleasant as that of milk. Scott, who was not a doctor and did not know much about chemistry or pharmacy, had visionary ideas.

The rapid development of medicine between 1890 and the entire 20th century put Scott’s Emulsion to the test, and it withstood the challenge and passed the scrutiny of specialists.

Although there is still extensive debate regarding the risks and benefits of cod liver oil, there remains no doubt about the efficacy of Scott’s Emulsion. It has even been sponsored by GlaxoSmithKline, one of the large companies dedicated to the pharmaceutical industry.

Composition and pharmacology

The chemical composition basically consists of vitamin A and vitamin D3 (22,610 International Units), cod liver oil, cholecalciferol 2 (261 International Units), phosphorus (642 milligrams), calcium (890 milligrams) and vehicles/excipients (100 milligrams). .

The specified amounts cover exactly every 100 milliliters and give the necessary nutritional contributions to the body, as long as the doses recommended by the doctor are followed.

In general, the pharmacology of Scott’s Emulsion, apart from being very rich in vitamins A and D and omega-3, contains nutrients that are easy for the body to assimilate. For this reason, adverse effects are not expected in most cases.

Vitamin A is converted to retinol and absorbed in the intestinal tract. It is then stored in the liver and gradually released.

Something similar happens with vitamin D, but instead of going directly to the liver, it goes to fat deposits. There it accumulates and is then expelled in the bile, although small amounts can come out in the urine.

Vitamin D is relevant for calcium to enter the body, which is why it is in the Scott Emulsion formula. Without this chemical element, bones and teeth do not form properly.

The phosphorus in Scott’s Emulsion is used for the body’s metabolism. For its part, omega-3 has two fundamental functions.

First, it participates in the sensory and neuromotor system of children, and second, it keeps the cardiovascular system in good condition in older people. This explains why Scott’s Emulsion can be consumed by the entire population.

Indications, Administration and Dosage

Scott’s Emulsion is often used for groups that may require higher amounts of vitamins A and D and omega-3s.

These people are the elderly, women with menopause, people with malnutrition problems, pregnant or lactating women (with the appropriate precautions from the doctor), growing children and babies who are teething (teething). .

Scott’s Emulsion is also recommended in patients with clinical disorders caused by deficiencies of phosphorus, calcium and vitamins A and D. Among these conditions are osteoporosis or hypovitaminosis. Also hypocalcemia, caused by low levels of calcium in the blood, and rickets, a condition of the bones.

Scott’s Emulsion is administered orally. Although the doses must be consulted with the specialist, they are normally daily.

The common dosage is usually based on taking 3 times a day for adults and children 6 years and older. Children from 2 to 6 years old should take the emulsion 2 times a day, and one-year-olds only 1 time a day.

The amounts consumed by patients should not exceed the indications prescribed by the doctor.

Precautions and contraindications

It is not recommended that Scott’s Emulsion be taken without the prior advice of a professional, especially during pregnancy or lactation. Excessive consumption can cause an overdose and the appearance of adverse effects that could trigger hypervitaminosis.

In addition, it should be consumed after having shaken the container well, so that the mixture of its ingredients remains homogeneous.

Potential adverse effects

None, except for overdose and allergy to the components of Scott’s Emulsion. In the first case, headache, irritability, anorexia and nausea may be experienced.


Anticoagulant medications and other vitamin supplements in which the metabolism of vitamin D is increased above normal levels.

For this reason, Scott’s Emulsion should not be consumed when treatment for malnutrition or vitamin deficiency is already underway.
